Set in the Victorian age in the fictional city of Anargal, we follow Arthur Artorias, a man stripped of his past, tortured, and forced to escape into isolation. Thought to be dead, he returns eight years later a changed man, disfigured, seeking answers and pursuing revenge.
Arthur won't carry out the assassination mission but he can't live without the pain-killing drugs from his benefactor; the benefactor also holds the secrets to Arthur's tragic past. He can't live with or without the benefactor. All Arthur can do is confront his benefactor no matter what the consequences are.
